๐ Monitoring Alerts
| Metric | Target | Alert |
|---|---|---|
| P95 Latency | <20ms | >50ms |
| Cache Hit Rate | >70% | <50% |
| Error Rate | <0.1% | >1% |

๐ง Quick Troubleshooting
High Latency (>100ms)?
โ Check KV cache hit rate
โ Verify service bindings connected
โ Monitor DO CPU usage
Cache Misses?
โ Verify TTL in code
โ Check KV key naming
โ Monitor KV get counts
Queue Backlog?
โ Increase max_concurrency
โ Reduce batch size
โ Check worker logs
Rate Limited?
โ Check tenant ID in rate limit
โ Verify limit: 1000 req/min per tenant
โ Scale via DO replication
